diagram of the V300B5H200AL layout and pinout

This is a fully isolated 300V to 5V DC/DC converter module, or "half-brick." It has 3000 volts isolation from input to output, has a standard footprint, and a wide voltage input of 180VDC-375VDC. The 5 Volts output is at 40Amps, giving 200 watts.

The short circuit protection is done by an automatic recovery "hiccough mode," meaning that when it detects an overload it tries to come on, then if the fault is still there it will shut off. This happens continually until the fault is corrected.

This is perfect for down converting 300 Volts from battery, electric vehicle or steel mill voltage sources to 5 Volts.
These are high quality, brand name USA converters, NAFTA eligible .
